Evaluating the Performance of Guardrail Systems for Installation in Georgia by Driving through Asphalt Layers: Phase I

Project Number:

13-21

Project Description:

Recent research suggests direct encasement of guardrail posts in a mow strip without leave-outs will cause excessive restraint at the ground line and prevent the post from functioning as intended in a vehicle crash. The Georgia DOT (GDOT) seeks alternatives for guardrail post installation that will allow the barrier to function as intended without resorting to costly grout-filled leave-outs at each post.
